This object is achieved by the subject matter having the features according to the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the figures.
According to a first aspect, the object is achieved by a household appliance having an exterior element which is arranged on an appliance outer side of the household appliance and has a lighting element having a light source for illuminating the exterior element, wherein the household appliance has a light-transmitting structural element having an outer side facing the appliance outer side and an inner side facing away from the appliance outer side, wherein the exterior element is arranged on the outer side of the light-transmitting structural element, and wherein the exterior element has an exterior layer in which at least one recess is formed, wherein the lighting element is arranged on the inner side of the light-transmitting structural element, and wherein the light source is configured for emitting light through the light-transmitting structural element and the recess in the exterior layer for illuminating the exterior element.
This has the technical advantage that a particularly effective illumination of the exterior element on the outside of the appliance of the household appliance is ensured without the need for a lighting device or a light guide being installed in the exterior element itself for this purpose.
In conventional household appliances, lighting and/or light guides are soldered into conventional exterior elements in order to be able to guide the light, for example, to the operating side of an operating panel of the household appliance. In order to ensure that the light guide is accommodated in the corresponding conventional exterior element, an additional printed circuit board must be fastened to the conventional exterior element, thereby increasing the installation effort.
In the domestic appliance according to the disclosure, a lighting element is used which is arranged on the inner side of the light-transmitting structural element within the domestic appliance facing away from the appliance outer side. The light source of the lighting element arranged within the household appliance emits light which passes through the light-transmitting structural element and through the cutout in the outer decoration layer of the outer decoration element to the appliance exterior of the household appliance. The light passing through the aperture of the outer decorative layer on the appliance outer side of the household appliance thus illuminates the outer decorative element.
A particularly visually attractive appearance of the outer side of the appliance of the household appliance can be ensured by the illuminated exterior element. Furthermore, it is possible for a user of the household appliance to visually highlight specific components on the appliance outside of the household appliance. In this way, the advantage is achieved that the user can advantageously recognize the respective component, for example an operating element of the household appliance, if the household appliance installation space is not sufficiently illuminated. Furthermore, dynamic content can be displayed by the exterior element, in particular by illuminating the exterior element, wherein the dynamic content may comprise, for example, a changing alphanumeric character string, such as, for example, a program remaining duration and/or an appliance status.
In particular, the light source can have at least one light-emitting diode, in particular an LED and/or an OLED. The LEDs and/or OLEDs can be dynamically controlled, emitting light with different colors and/or different intensities, so that in particular a uniform illumination of the exterior element can be ensured.
A household appliance is understood to be an appliance for household use. It may be a large household appliance, such as a washing machine, a washer-dryer, a dishwasher.

The light source can be arranged in the light-transmitting structure element, and the light-guiding element can be arranged in the light-transmitting structure element in such a way that the light source is arranged in the light-transmitting structure element. After the light has been guided through the light-guiding element, the light can be coupled out of the light-guiding element on the side of the lighting element facing the light-transmitting structural element, advantageously through the coupling-out face of the light-guiding element. The outcoupled light can then be emitted through the light-transmitting structural element and through the opening in the outer decoration layer to illuminate the outer decoration element. In particular, the coupling-out surface is larger than the coupling-in surface and the coupling-out surface is arranged offset with respect to the coupling-in surface, which achieves the advantage that the light guided by the light-guiding element can be coupled out of the coupling-out surface over a particularly large area, so that a particularly large-area and uniform illumination of the exterior element is produced and regions (hot spots) which are not uniformly illuminated in terms of brightness can be avoided.
In an advantageous embodiment of the domestic appliance, the lighting element has an electrically conductive element, in particular a film conductor or a Printed Circuit Board (PCB), wherein the light source is electrically connected to the electrically conductive element and the electrically conductive element is in particular connected to a power supply of the domestic appliance.

Alternatively, the exterior element 121 can comprise one or more exterior elements 121 in the sense of the present disclosure, which are arranged at different locations on the appliance exterior 107 of the domestic appliance 100 and can have different shapes and geometric configurations.
Fig. 2 shows a schematic illustration of an exterior element 121 and a lighting element in a household appliance 100 according to a first embodiment in a sectional view. In the second embodiment shown in fig. 2, the exterior element 121 is arranged on the appliance exterior 107 of the domestic appliance 100, in particular on the front side 109 of the domestic appliance 100, and the exterior element 121 is arranged on the operating panel 123 of the operating element 119 of the domestic appliance 100. The exterior element 121 can in this case comprise, in particular, a colored or uncolored transparent plastic.
The household appliance 100 has a light-transmitting structural element 125 on the front side 109, which is in particular designed as an operating panel insert and is connected to the operating panel 123. The exterior element 121 has an exterior layer 127, which is arranged on an outer side 129 of the light-transmitting structural element 125.
As shown in fig. 2, the outer side 129 of the light-transmitting structural element 125 is printed or decorated with an outer decoration layer 127 by means of an in-mold decoration process (IMD). The outer decoration layer 127 has a region in which the outer decoration layer 127 is light-transmitting, for example hollowed out, and thus reflects the contour of the outer decoration element 121.
An illumination element 133 is arranged on an inner side 131 of the light-transmitting component 125 opposite the outer side 129 of the light-transmitting component 125. The lighting element 133 can be connected to the inner side 131 of the light-transmitting structural element 125 in a form-fitting, force-fitting and/or material-fitting manner, in particular by an adhesive, welded, clipped and/or clamped connection.
The lighting element 133 has a light source 135, which is designed to emit light 137, wherein the light source 135 has, in particular, a diode, for example an LED and/or an OLED, which emits light. The light source 135 is electrically connected to an electrical conductor 139, in particular a thin film conductor or a Printed Circuit Board (PCB). The electrical conductor 139 is connected in particular to a power supply source, not shown in fig. 2, of the household appliance 100.
The lighting element 133 has a side 141 facing away from the light transmissive structural element 125 and a side 143 facing towards the light transmissive structural element 125. The light source 135 is arranged on a side 141 facing away from the light-transmitting structural element 125.
The light guiding element 145 extends within the lighting element 133 from the light source 135 to a side 143 of the lighting element 133 facing the light transmissive structural element 125. The light-guiding element 145 has an input surface 147, via which the light 137 emitted by the light source 135 can be input into the light-guiding element 145, and the light-guiding element 145 has an output surface 149, which is designed for outputting the light 137 out of the light-guiding element 145, wherein the output surface 149 is larger than the input surface 147, and the output surface 149 is arranged offset, in particular with respect to the input surface 147, such that a homogeneous light output is ensured.
As shown in fig. 2, the light-guiding element 145 has a receptacle 151, in particular a recess, which is designed to receive the light source 135. The coupling-in surface 147 therefore surrounds the light source 135 at least in sections, in order to couple the light 137 into the light-guiding element 145 particularly effectively. Since the coupling-out surface 149 extends over a large area along the side 143 of the lighting element 133 facing the light-transmitting structural element 125, the light 137 can then be coupled out of the light-guiding element 145 through the coupling-out surface 149, and the coupled-out light 137 can be efficiently introduced into the light-transmitting structural element 125.
The light-transmitting structural element 125 is formed from an at least partially light-transmitting plastic, such as Acrylonitrile Butadiene Styrene (ABS), polymethyl methacrylate (PMMA), and/or Polycarbonate (PC), and light 137 is advantageously transmitted through the light-transmitting structural element 125 on the basis of the light transmission.
At least one recess 153 is formed in the outer decorative layer 127 of the outer decorative element 121, through which light that has penetrated the light-transmitting structural element 125 can emerge to the outside and can thus advantageously illuminate the outer decorative element 121. The recess 153 has a circumferential recess edge 15, which delimits the recess 153.
Fig. 3 shows a schematic illustration of an exterior element 121 and a lighting element 133 in a household appliance 100 according to a second embodiment in a sectional view.

The household appliance 100 has a light-transmitting structural element 125 on the front side 109, which is designed as an operating panel insert and is connected to the operating panel 123. The exterior element 121 can in this case comprise, in particular, a colored or uncolored transparent plastic.
The exterior element 121 has an exterior layer 127, which is arranged on an outer side 129 of the light-transmitting structural element 125. An illumination element 133 is arranged on an inner side 131 of the light-transmitting component 125 opposite the outer side 129 of the light-transmitting component 125. The lighting element 133 can be connected to the inner side 131 of the light-transmitting structural element 125 in a form-fitting, force-fitting and/or material-fitting manner, in particular by an adhesive, welded, clipped and/or clamped connection.
The lighting element 133 has a light source 135, which is designed to emit light 137, wherein the light source 135 has, in particular, a diode, for example an LED and/or an OLED, which emits light. The light source 135 is electrically connected to an electrical conductor 139, in particular a thin film conductor or a Printed Circuit Board (PCB). The electrical conductor 139 is connected in particular to a power supply source, not shown in fig. 3, of the household appliance 100.
The lighting element 133 has a side 141 facing away from the light transmissive structural element 125 and a side 143 facing towards the light transmissive structural element 125. The light source 135 is arranged on a side 143 facing the light transmissive structural element 125.
The light source 135 is configured for emitting light in a direction of a side 141 of the lighting element 133 facing away from the light transmissive structural element 125. The lighting element 133 has a reflective element 157 for reflecting light 137, which is arranged on a side 141 of the lighting element 133 facing away from the light-transmitting structural element 125.
The reflective element 157 is shaped as a cover of the lighting element 133, in particular as a light-blocking cover, which in particular has at least one contour to ensure effective reflection of the light 137. The reflective element 157, which is designed as a cover, reflects light 137 introduced in the direction of the side 141 of the lighting element 133 facing away from the light-transmitting structural element 125 in the direction of the side 143 of the lighting element 133 facing the light-transmitting structural element 125.
The lighting element 133 has a light scattering element 159, in particular a light scattering film in the lighting element 133, a contoured surface of the lighting element 133, and/or a light scattering layer in the outer layer 127, and/or a light scattering print of the lighting element 133. The light 137 reflected by the reflective element 157 is scattered by the light scattering element 159 to obtain dispersed light 137, wherein the dispersed light 137 can then pass through the light transmissive structural element 125.
At least one recess 153 is formed in the outer decorative layer 127 of the outer decorative element 121, through which light that has penetrated the light-transmitting structural element 125 can emerge to the outside and can thus advantageously illuminate the outer decorative element 121. The recess 153 has a circumferential recess edge 155, which delimits the recess 153.
The advantage of the exterior element 121 illuminated by the lighting element 133 is a flexible degree of freedom in the construction of the exterior element, since it can also be arranged on curved surfaces and thus ensures a simple installation. If LEDs or OLEDs are used as light sources 135, the LEDs or OLEDs can be dynamically manipulated and can emit light 137 with different colors and/or different intensities, and thus ensure uniform illumination. Furthermore, the exterior finishing element 121 can be formed to have a linear profile or an arcuate profile.
All the features illustrated and shown in connection with the various embodiments of the invention can be provided in the subject-matter according to the invention in different combinations to achieve their advantageous effects simultaneously.
The scope of the invention is given by the appended claims and is not limited to the features set forth in the description or shown in the attached drawings.
